Even the simplest roof needs not only careful preparation, but also installation. Otherwise, you risk admiring the leaks in the ceiling and start unscheduled repairs. The more complex the roof structure, the more carefully every detail must be finished. On large and complex roofs, there are many elements, the so-called roof nodes, the design and decoration of which requires an attentive and serious attitude.
So what are these nodes, and how should each of them be finished?
What is the roof made of?
Your roof is not just a beautiful finishing touch to your home.It is designed to reliably protect the interior of the building for many years.
Starting with the rafter system, continuing with multi-layer insulation from all weather influences, ending with the finish coating - your roof is quite complex.
The more complex and pretentious it is, the more nodes it will have. This concept refers to all joints and counter connections with other elements.
Exits of chimneys and ventilation pipes, antenna outlets, lightning rods, slope joints, junction with neighboring slopes or walls, ridge roof elements, window openings - all this is your roof nodes.
The more so-called "bells and whistles" - the more attention they need to pay during installation.
Before you cover the roof, you mount the truss system. Using the walls of the building as the main support, you erect a hanging rafter system.
If your foundation is of a columnar type, or there are additional walls, then a layered rafter systemwhere the rafters also rest on other, additional walls.
Roofing pie consists of the following elements:
- The system of rafters from boards or timber.
- Vapor barrier layer.
- Warming layer.
- waterproofing layer.
- Crate.
- Finish coating.
After the design of the roofing cake, the final coating is mounted. And here you need to be especially careful, because the coating must not only be well fixed, but also sealed in weak places.
The adjunction of tiles to the chimney, antenna outlets, ridge, valley, roof parapet, observation windows - all this is made out with additional elements.
Note! Special aprons or clamping strips are produced that strengthen the joints. Their design is so simple that you do not need outside help for installation. Aprons are attached with nails or screws in the right places, and then, for greater reliability, the fasteners are coated with sealant. Or screws with a special rubber washer are used, which creates a sealed fastener.
This method of strengthening the docking points gives a wonderful effect. Water will no longer penetrate under the roof, and the joint will take on a finished look.
During installation and finishing work, it is important to take into account the weight of the roof, which affects the condition of the roof.
For example, for coatings made of ceramic tiles, which are known to be quite heavy material, not only an additionally reinforced rafter system is performed.
In places of roofing nodes, joints and junctions, you need to be especially careful. A poorly fixed shingle may move and the joint will begin to leak. Therefore, it is important to carefully arrange all nodes without exception.
Let's remember what are the typical roof nodes, the most common on almost all roofs.
Main roofing units
- Longitudinal seams in metal roofing. . The seam method of their connection creates sufficient tightness.
- Skate. It is often a weak point near the roof, so it must be decorated with additional reinforcing elements.
- Roof cornices. Installed to protect walls from water, it must be protected by itself, for a long and reliable service.
- Chimney. It must be sealed with special aprons.For strengthening and sealing, cutting of the roof is also perfect - a special silicone passage in various colors. A special metal strip on its edge allows you to give the element the desired shape.
- Parapet gable roof. Perimeter fencing, which is installed for security purposes. The places of his meeting with the roof itself may also begin to leak. Therefore, here you need to take care of the protection of the joints.
- Valleys. They also need to be decorated with the necessary accessories.
- Viewing windows. The processing of their joints with the roof should be treated with particular care. Such outlets have many weak points where unexpected leaks are likely.
- ventilation outlets. They are trimmed with clamping strips and the seams are covered with sealant. Roof cutting of the required shape is also perfect.
- Antenna outputs. There are many varieties of accessories for finishing and sealing them.
- The window sill is finished with a window sill that does not allow water to enter.
- Joints with adjacent slopes, as well as a wall. They are reinforced with clamping strips, or specially provided materials. Must be treated with sealant.
- Drain funnels. Usually mounted on flat roofs. They need a roofing apron or decoration with silicone putty.
How to handle nodes on the roof
As you can see, even in the simplest roof there are quite a few additional elements. Roofs with steep slopes are less prone to leaks, however, they also have enough weak points.
Note! The more complex the roof structure, the more areas where water can accumulate. No matter how well the waterproofing is done, water can get into the under-roof space.The most vulnerable can be considered the ridge and the junction with the chimneys, as well as the recesses where two slopes meet. Debris and leaves often accumulate there, and they retain water, causing it to stagnate.
For chimneys, it is best to use a roofing apron, which is easy to adapt to the individual shape of the pipe.
Metal aprons are preferably welded to the coating. The joints of its elements are also better welded to each other.
Then you get a perfectly solid construction that can last a very long time. Manufacturers produce all finishing elements for processing key points for roofs of various colors.
Therefore, it is possible to choose an accessory not only of the desired design, but also of a convenient shade. Thus, the roof after final processing will acquire not only a finished look, but also become more attractive.
If you have no experience, and you do not know how to fix the roof, invite specialists, or at least consult with them. After all, a very serious approach is important for such work.
Just imagine that your roof is mounted perfectly, but you still see a leaky ceiling from time to time. Roof inspection fails, and one has to rack one's brains to find out where the leak is.
In order to avoid these troubles, it is necessary immediately after the installation of the roofing pie to simply process the roof nodes in accordance with all the rules.
Competent finishing of especially vulnerable areas will give a striking effect. The only thing that is required is to inspect the roof from time to time in order to identify and eliminate problems in a timely manner.
